2. Key Concept Definitions | 核心概念定义解析

Power is the ability of an individual or group to influence or control the behaviour of others, even against resistance.

权力是个人或群体影响或控制他人行为的能力，即使遇到阻力也能实现。

Authority is legitimate power; it is the right to make decisions and expect obedience because the position is accepted as lawful.

权威是合法化的权力；由于职位被认可为合法，因此拥有决策并要求他人服从的权利。

Legitimacy is the belief among citizens that a government has the right to rule, often based on consent, tradition, ideology or performance.

合法性是公民相信政府有权统治的信念，通常基于同意、传统、意识形态或政绩。

Sovereignty is the supreme authority of a state to govern itself without external interference.

主权是国家在不受外部干涉的情况下进行自我治理的最高权力。

When a short definition question asks for one term, give the core meaning first, then add one brief example or qualifying phrase to show understanding.

当简答定义题要求解释一个术语时，先写出核心含义，再补充一个简短例子或限定语以展示理解。

3. Forms of Government | 政府形式

A democracy is a system in which power is held by the people, either directly or through elected representatives.

民主制是权力属于人民，由人民直接或通过选举产生的代表行使权力的制度。

An authoritarian regime concentrates power in a leader or small elite and restricts political pluralism, opposition and civil liberties.

威权政体将权力集中在领导人或少数精英手中，限制政治多元化、反对派和公民自由。

A constitutional monarchy has a monarch as head of state whose powers are limited by law, while an absolute monarchy gives the monarch unrestricted power.

君主立宪制的君主是国家元首，但其权力受法律限制；而绝对君主制赋予君主不受限制的权力。

A republic has an elected or appointed head of state rather than a hereditary monarch, and sovereignty formally rests with the people.

共和国拥有经选举或任命产生的国家元首，而非世袭君主，主权在形式上属于人民。

Federal states divide sovereignty between central and regional governments; unitary states concentrate authority at the centre, although some powers may be delegated.

联邦制国家在中央和地区政府之间划分主权；单一制国家将权力集中于中央，尽管部分权力可以下放。

4. Comparing Democratic and Authoritarian Systems | 民主与威权制度比较

Democratic systems are characterised by free and fair elections, protection of rights, separation of powers, an independent judiciary and a free media.

民主制度的特点是自由公正的选举、权利保护、权力分立、独立司法和自由媒体。

Authoritarian systems usually limit opposition, control information, weaken the judiciary and centralise decision-making in a leader or ruling party.

威权制度通常限制反对派、控制信息、削弱司法，并将决策权集中于领导人或执政党。

In an essay, avoid listing features in isolation; link each feature to outcomes such as accountability, representation, political stability or economic policy.

论述题中，不要孤立罗列特征；要把每个特征与问责、代表性、政治稳定或经济政策等结果联系起来。

Example link: regular elections create accountability because voters can remove unpopular leaders, whereas the absence of competitive elections weakens public control over government.

示例联系：定期选举产生问责机制，因为选民可以罢免不受欢迎的领导人；而没有竞争性选举则会削弱公众对政府的控制。

5. Elections and Voting Systems | 选举与投票制度

First-past-the-post awards a seat to the candidate with the most votes in each constituency, even if the winner receives less than 50 per cent of the vote.

简单多数制把席位授予每个选区得票最多的候选人，即使获胜者得票低于百分之五十。

Proportional representation allocates seats according to each party’s share of the total vote, making smaller parties more likely to gain representation.

比例代表制按各党占总票数的比例分配席位，使小党更有可能获得代表权。

For a data question, show the calculation step by step before explaining what the result means for party strength.

数据题要先展示计算步骤，再解释结果对政党力量意味着什么。

seats = 420,000 ÷ 2,000,000 × 100 = 21

This means a party with 420,000 votes out of 2,000,000 valid votes would win 21 seats in a 100-seat proportional system.

这意味着在有效选票为 2,000,000 张时，获得 420,000 票的政党在 100 个席位的比例代表制中将获得 21 个席位。

Advantage of first-past-the-post: it tends to produce a strong single-party government with a clear mandate.

简单多数制的优点：往往产生有明确授权的强大一党政府。

Disadvantage of first-past-the-post: many votes can be wasted because only the winning candidate’s surplus or all losing votes do not elect anyone.

简单多数制的缺点：许多选票可能被浪费，因为落选候选人的选票无法选出任何代表。

Advantage of proportional representation: it reflects voter preferences more fairly and increases minority representation.

比例代表制的优点：更公平地反映选民偏好，并提高少数群体的代表性。

Disadvantage of proportional representation: coalition governments may be unstable and decision-making can be slower.

比例代表制的缺点：联合政府可能不稳定，决策速度可能较慢。

6. Political Parties and the Policy Spectrum | 政党与政策光谱

Left-wing parties generally support greater economic equality, state intervention, progressive taxation and expanded social welfare.

左翼政党通常支持更大的经济平等、国家干预、累进税制和扩大社会福利。

Right-wing parties typically favour lower taxes, free markets, private enterprise, deregulation and traditional social values.

右翼政党通常支持低税收、自由市场、私营企业、放松管制和传统社会价值观。

The centre represents a moderate position combining elements of both left and right, often appealing to swing voters.

中间立场代表结合左右翼要素的温和主张，往往吸引摇摆选民。

A multi-party system can increase representation but often requires coalition government; a two-party system usually produces clearer mandates but narrower choice.

多党制可以增加代表性，但通常需要联合政府；两党制往往产生更明确的授权，但选民选择范围较窄。

When using the left-right spectrum in an answer, remember it is a simplification: parties may be liberal on social issues but conservative on economic issues.

在答案中使用左右光谱时，要记住这是一种简化：政党可能在社会议题上偏自由，但在经济议题上偏保守。

7. Human Rights and Civil Liberties | 人权与公民自由

Human rights are universal entitlements that belong to all people, such as the right to life, freedom of expression and freedom from torture.

人权是所有人与生俱来的普遍权利，例如生命权、言论自由和免于酷刑的权利。

Civil liberties are protections against state interference, including freedom of assembly, freedom of religion and the right to a fair trial.

公民自由是保护个人免受国家任意干涉的权利，包括集会自由、宗教自由和接受公正审判的权利。

In source-based questions, identify which right is being limited, who is responsible, whether the limitation has a legal basis, and whether it is proportionate.

材料题中，要识别哪项权利受到限制、责任方是谁、限制是否有法律依据，以及限制是否相称。

A strong answer will also distinguish between negative rights, which require the state not to interfere, and positive rights, which require state action to provide a service.

高分答案还会区分消极权利与积极权利：消极权利要求国家不干涉，积极权利要求国家采取行动提供服务。

8. Rule of Law and Judicial Independence | 法治与司法独立

The rule of law means that everyone, including government officials, is subject to the law and no one is above it.

法治意味着包括政府官员在内的所有人都受法律约束，没有人凌驾于法律之上。

Judicial independence requires judges to decide cases free from political pressure, bribery or personal bias, and to be protected from unfair dismissal.

司法独立要求法官在不受政治压力、贿赂或个人偏见影响的情况下裁决案件，并受到免于不公平解职的保护。

A strong case study can refer to the separation of powers: the legislature makes law, the executive implements law, and the judiciary interprets and applies law.

有力的案例可以联系权力分立：立法机关制定法律，行政机关执行法律，司法机关解释和适用法律。

If an exam question asks why judicial independence matters, explain that it upholds fair trials, protects rights against executive abuse and maintains public confidence in the legal system.

如果考题问司法独立为何重要，要解释它维护公正审判、保护权利免受行政滥权侵害，并维持公众对法律体系的信心。

9. International Organisations and State Sovereignty | 国际组织与国家主权

International organisations such as the United Nations promote cooperation, peace and development, but membership can require states to limit some sovereign decision-making.

联合国等国际组织促进合作、和平与发展，但加入这些组织可能要求国家限制部分主权决策。

Joining a regional body such as the European Union involves pooling sovereignty in areas like trade, migration or competition policy.

加入欧盟等区域组织意味着在贸易、移民或竞争政策等领域集中共享主权。

A key tension is that international human rights law may conflict with state claims that domestic matters are internal affairs.

一个关键矛盾在于国际人权法可能与国家关于国内事务属于内政的主张发生冲突。

When evaluating this tension, use both sides: sovereignty protects national self-determination, but unchecked sovereignty can allow human rights abuses without external accountability.

评价这一矛盾时要兼顾两面：主权保护民族自决，但不受制约的主权可能允许侵犯人权而无需承担外部责任。

10. Source-Based Question Technique | 材料题答题技巧

Read the question first, then read the source to identify the author, audience, purpose and tone.

先读题目，再读材料，找出作者、受众、目的和语气。

Use short quotations from the source as evidence, but follow each quotation with your own explanation and link to the question.

使用材料中的简短引文作为证据，但每条引文后都要加上自己的解释，并回扣题目。

For an 8-mark source question, produce two developed points: one based closely on the source and one drawn from your wider knowledge of the topic.

对于 8 分材料题，要写出两个展开的论点：一个紧密基于材料，另一个来自你对主题的更广泛知识。

If the question asks you to assess reliability, consider the source’s origin, purpose, selection of evidence and whether other sources would support or challenge it.

如果题目要求评价材料的可靠性，要考虑其
